Do you have a topic that is an immediate deal breaker if a manga series you were already reading suddenly featured that topic, such that you would stop reading the series (even if it was "tastefully" done)? For example: religion, rape, etc.

Orbiting serenely above a long-ago poisoned earth, the last bastion of human civilization is the space colonies. After a terrorist attack, the colonists are forced into exile on the blighted planet below. In the confusion, a young mother is separated from her family and is flung into a bleak, uncertain future... But Sarah will not rest until she finds her children.

I thought that the title was a bit unfortunate, and the premise a bit... lame, maybe? I don't really like familial themes much, but after reading it, I must admit - it's a solid manga, perhaps a bit too focused on the savageness of humanity, and including a few somewhat disturbing themes such as rape, but all in all - it's good, and interesting.
